With more equipment stuffed into my rack, I can no longer fit my Oreas. (sniff)
Now I’m asking for recommendations on isolation devices that are less than 0.75" high.
On two shelves, I have PS components stacked, so max weight required is 40 lbs.
PS—I always find my best test for effectiveness of a tweak is to go backwards and listen and the absence of the Oreas made a substantial difference. I’d love to find something equally effective.
Thanks
Ron
Ron, one suggestion I have is the ebony hemispheres that Herbie’s Audio Lab sells. They are low enough for you and they have an interesting effect as isolation components.
Great for giving center channel or bookshelf speakers a lift at the front or back for some tilt. Tilt angle can be adjusted/increased by moving the domes incrementally toward the opposite side. Can also be used as component feet. 1" (25.4mm) diameter by 1/2" tall.
$2.89 ea.

Thanks Lonson! I knew you’d know.

The also work very nicely with the “Iso-Cup” base from Herbie’s and together they are just about 3/4" . . . . A possible combo that may work very well. (I like the “domes” in the Iso-Cup a lot).

Tenderfeet are .65” tall…
They are available in a taller variant, and a denser variant is available for heavy components. Use these for my Oppo UDP, Anthem MRX AVR, and a PS Audio P5 Power Plant. Alto Extremo footers on the rest.
Have you considered a second rack? Audio Advisor sells a good solid 4 shelf rack for $100.
Depending on the component I have used rubber stoppers sold at hardware stores. They come in many sizes and heights.
Although the Herbie’s products are a good value too.
Yes but there are forces much more powerful than me at play. And she’d prefer it this way…
So, I have a new rack with much more space and now I can once again use footers. At the suggestion of one of our all knowing, all seeing, sooth saying experts who shall remain anonymous (LONSON), I tried VooDoo Iso-Pods. Ain’t cheap but a worthwhile investment, (he told himself whilst looking at his credit card bill).
Their effectiveness in order is clearly:
DSD SR. (a major improvement)
DMP
control chassis of my preamp
power chassis of said preamp
These truly give an improvement in clarity and detail.
They have no effect that I can detect under my power amp, however.

You’ve saved some money if they don’t have an effect on the power amps! I have them under all my components now. . . except the TV. (Maybe one day!)* I love how they are “neutral” but improving. . . most isolation components I’ve tried don’t seem as neutral. Glad you are finding them a positive improvement.
*Edited to add: Maybe one day I’ll try Iso-Pods under the TV but recently I placed the TV on a PS Audio PowerBase I bought from RonP and using the top of the line PS Audio AC12 HDMI cable bought from RonP. I thought the TV looked and sounded great sitting on a 4 " maple platform from Mapleshade Audio and using the PS Audio AC-12 power cord, but it’s gone up yet another level . . . even getting additional praise from my wife, which is RARE.
No Ron… you can’t have your Orea’s back

Hey Lonson what version rack do you have, I am thinking about the v5 with the one 4 inch shelf on top for the real heavy stuff.
I have two. Initially, about 14 years ago, I bought a Ver. 2. Then about 7 years ago I bought a Ver. 3 with three 2" shelves.
Are you happy with them quality wise? The shipping cost is painful but hoping this is a once in ten year type purchase
Very much so. I love them. I’m committed to them.
Awesome, thank you so much!
Most isolation products are made Sorbothane and hemispherical feet can be found on Amazon for a few $ for a pack of 4 or 8.
If you don’t want to spend anything, cut up the inserts from a pair of old sports shoes, they are usually made of Sorbothane.
The only isolation product I have found to demonstrably work - tested using a vibration app (Seismometer on iOS) - are Townshend isolation podiums and bars. They also do things that isolate the entire rack.
Sorbothane has some dampening effect, but not isolation.
Save time and a fortune, Kellet, Se. Shakeaway. In washing machine aisle at lowes home improvement . Or on amazon. lowes will match any “reasonable” online competitor. got my last set for $26. the new set is simply colored blue, no changes in sonic tuning per the manufacturer. Of course I am sure some will hear such. I have replaced stillpoints 6 throughout with these. I feel they are the best at “any” cost" of course “YMMV”.
@RonP - The shortest height I have seen in acoustic isolation is 0.9in high. I use these for my very small components. A little higher than 0.75in; however, they might work. I have asked the manufacturer for the data as to the band they cover. They just give max load per puck. They said they will be coming out with the data a few months ago, still waiting.

If they sell Sonic Design damping feet where you live try to get some of those. 
I’m pretty sure this idea has been mentioned before, but a guy in my audio group, whose system is to drool over (Zesto and Watt/Puppy’s) replaced all his footers with bicycle tubes. Looks awful, but he claims that they’re the best.
